Patented Oct. 22, 1935 UNITED STATES PATENT OFFICE MOVABLE SPLIT BED FOR FLAT BED PRINTING PRESSES 16 Claims.

This invention relates to a movable split bed for flat bed printing presses and has for its object to so construct the bed as` to enable convenient access thereto to expeditiously change a form 5 when occasion requires.

A further object of the invention is to provide, in a manner as hereinafter set forth, a bed of the class referred to so constructed and arranged whereby the form carried by the bed may be readily removed from under the printingcylinder when changes are desired.

A further object of the invention is to provide.. in a manner as hereinafter set forth, a bed of the class referred to so constructed and arranged whereby a form may be quickly and conveniently changed when desired.

A further object of the invention is to provide, ln a manner as hereinafter set forth, a bed of the class referred to including a slidably mounted, latchable form carrier permitting for conveniently and expeditiously changing a form when occasion requires.

A further object of the invention is to provide, in a manner as hereinafter set forth, a bed o-f the class referred to including a slidably mounted, latchable, extendible form carrier permitting for conveniently and expeditiously changing a form, and including means to prevent the form carried thereby from sliding off therefrom during the moving of the carrier to form changing position.

A further object of the invention is to provide, in a manner as hereinafter set forth, a bed of the class referred to including an extendible form carrier and adjustable means coacting with the form retaining means for releasably anchoring the form upon the carrier.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a bed of the class referred to which is comparatively simple in its construction and arrangement, strong, durable, compact, conveniently assembled, readily repaired when occasion requires, thoroughly efficient for the purpose intended thereby, materially decreasing the time now required to change a form enabling the use of a full type form, i. e. the full capacity of a press without the employment of the conventional quoin, and inexpensive to manufacture.

To the above ends essentially, and to others which may hereinafter appear, the invention consists of such parts, and such combination of parts which fall within the scope of the invention as claimed.

Figure 4 is a perspective View of a wedge or locking block,

Figures 5 and 6 are sectional details illustrating Y the track members or cylinder bearings, and 10 Figure 7 is a fragmentary View in elevation showing the latching means for the carrier.

The bed, generally indicated at 6, is of the reciprocatory type and, as well known, is associated with an impression cylinder l which travels on the top of the bed for the purpose of printing from the form 8.

The bed includes a pair of spaced outer oblong supports Il, I0, a pair of spaced inner oblong supports II, I2 arranged between the sup- 20 ports 9, IIB. The supports are of the same width, height and length. The ends of the supports are rabbeted to form transverse aligning shoulders I3, I4 arranged in close proximity to the lower faces of the supports. A connecting mem- 2'5 ber I5 is mounted upon the shoulders I3 and is connected to one end of the said several supports above the shoulders I3. A connecting member I6 is mounted upon the shoulders I4 and is connected to the other end of the` several supports 30 above the shoulders I3. Two spaced parallel sets il, EB of upstanding brace members are arranged between and connected to the supports S, It, II and I2. The brace members are flush with the tops of the supports and have their bottoms ar- 35" ranged above the lower faces of the supports. The brace members of the set I'I oppose in spaced relation the connecting member I5. The outer brace members of the set Il are provided centrally of the top thereof with rectangular cut- 40'? outs I9 for a purpose to be referred to. The brace members of the set I8 oppose in spaced relation the connecting member It. The outer brace members of the set E8 constitute stops for a purpose to be referred to.

The supports II and I2 centrally of the tops thereof, are formed with V-shaped grooves 2I'I extending from one end to the other thereof. The top edges of members I5, It have V-shaped notches forming continuations of the grooves 20. 50

Secured upcn and to the tops of the supports 9, II) are track members or cylinder bearers 2|, 22 respectively for the impression cylinderl. The track member 22.- is of angle-shape in cross-section and formed of a vertical leg 23 and a hori'- 55 zontal leg 24 integral with the outer end of and extending inwardly from leg 24. The track mem- Vbers are hanged at their bottom, as at 25 with respect to track member 2i and as at 26, 2l with respect to member 22.V The track members 2l,V 22 are oppositely beveled, as at 28, 29 respectively forming in connection with supports 9, i9 guide groovesY or passages Sii, 3l respectively for aV 22 is provided with transversely extending spaced threaded openings 53 extending from the outer side thereof and communicating with the top of the groove 32. The openings 33 incline downwardly throughout from their outer to their in- Y ner ends. n

Connected to the outer face of the member I and extended therefrom is an inking plate element 34 including a vertical inner part 35 extending above theV top edge of member I5 and Y formedV with a plurality of spaced endwise opposed rectangular openings V36 disposed above member I5. 5 Y Y The body-structure of the bed has been described as a series or" separate elements secured jtogether, but it is obvious that the supports, connecting members, brace'mernbers, track members Yand ink'plate structure may be set up from a single casting, or that certain of the elements may be cast together and the other element or elements secured therewith.

The bed includes an extendible carrier 39 for the form S and which consists ofY a plate 49 of a size to extend from the bottom of one bevel por- Vtion 28'to thebottom of the other bevel portion 29 'and to extend from the outer face oi member Vois I6 tothe outer face of member I5. The. plate 49 has'its side edges oppositely beveled, as at 4I, 42. kr'Ihe said side' edges of plate 49 extend into the guide passages formed by the bevels 28, 29 in connection with the supports 9, I0. The plate 49is slidably Vmounted uponthe inner portions of the tops of the supports 9, I9 and is also slidably mounted upon the tops of the supports I l, I2 as well as the tops of the. sets of brace members. The plate 40 has secured to its inner edge a plurality of upstanding spaced stops 43 to prevent the shifting orf of the form from the rear end of carrier 59, when the latter is being moved to its extended position for the purpose of changing a form. When the carrier 39 is in non-extended position and supporting a form to be printed y from, the stops 43 are arranged within the. openings-36. Therstops 43Ywill also act to pull the form along with the carrier when the latter is being moved to extended position for form changing. VThe4 carrier 39 at its outer end of its inner face is provided with a transversely extending cutout toprovide a ledge 44 for a purpose to be referred to. The lower face of plate 40 is formedV with spaced parallel guide strips 44 Vof V-shape cross section which ride in the grooves 20. The

Y lower face of plate 40 has 'secured thereto depending abutments 45 which, whenV the carrier Y Y is being extended; pass through openings I9to abut the outer brace members I8, whereby these :latter constitute stops for arresting the outward shifting of the carrier. Y

VWith respect to Figure v1 the form 8 is shown clamped on the carrier 39 when too large to use a chase andthe means for clamping it will now be described. f Y

Threadedly engaging with the walls of the opening 33 are combined adjusting and clamping vscrews 46 for engaging spaced beveled parts at the upper inner corner 46 of a steel block 4'I, to force the latter against an end of'form VV8. The block 4'I Vis arranged within and extended from groove 32. A steel bar 4ll bears against one side of form 8. The bar 4'I extends from one track member to the other and bears against V the stops 43. The form 8 at its other end bears against the inner face of track VmemberV 2|.'V At Y .the other side of form 8.is arranged a wooden bar 50 and spaced from the latter is a steel bar 5I. Interposed between the bars 59 and 5I are quoins 52, and interposed between the bar 5I and clamps is the wood furniture 53 which is arranged over ledge 44.

There are times whenV forms are Aof such size that a chase cannot be placed around them. In that case steel bars are placed in frontand in back of the type form .and quoins are Vused'to lock or squeeze the'type securely on the bed.

When there is no room left for quoins on bearerV side a sort of wedge is used, but this is very unsatisfactory as it will jump out at times during the rapid motion of the press. kThis objection is overcome by placingY the block 4l in the Vgroove o Y 32 as the upper wall thereof will prevent the jumping out of the wedge. u Y The track members 2l, 24 have their upper edges formed'with a toothed rack 54. Y

The carrier 39 is latched in formholding position by spaced clamps 55 which are pivotally connected to the member I6 and Vcoact with the Iwedging bar 56 which may be welded or otherwise secured to the' lower portion ofthe cuter face of member I6. The clamps 55 are to be swung upwardly binding or locking the plate 40 and in turn hold the wood furniture 53 while the quoins 52 are tightened. The Vbottoms of the clamps 55 coact from'a wedging standpoint with bar 56 whereby they will be held in clamping position relative to plate 40. The clamps 55 are eccentrically pivoted and have roundedy lower ends. Although it is to be understoodrthat any suitable means may be employed Vfor latching the carrier 39 in form holding position with respect to the other elements of the bed.

The plate 40 has its outer end formed with anY apertured extension 5'I for use toV move the carrierV in opposite directions upon its supportingV The supports 9, I0, I I, I2, bracing members I 1, Y

I 8, and track members 22, 23 constitute a supi,"

porting structure for the carrier and for the ink plate element.
